Leners Patent No. 82,621, dated September 29, 1868.

IMPROVEMENT IN IIAMMBRS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, GEORGE W. HUBBARD, of Lowville, in the county .ofLewis, in the State of New York, have invented a new and improvedNail-Clamp Attachment for Hammers, that'enables me to drive nails atinconvenient reachvfromboth hands, or in thecase such as when it becomesnecessary to hold a board or timber' withone hand, or for the use ofone-armed persons; and I do hereby declare that the following is a. fulland' exact description thereof, reference being had to the accompanyingdrawings, and'to the letters of reference thereon, in which-.- A

Figure 1 is a view of the hammer and nail-clamp, with the nail clampedfor driving.`

Figure 2 shows the nail-clamp attached to the hammer, without the nail.

Figure 3 represents the Vclamp removed.

A B, the hammer-head. v

1C, chamber sunk in the socket of' hammer,'to receive the nail-head.

D, the nail clamped.

E, the clamp.

F, screw for securing clamp.'

- G, clamp-spring. y

H,'thumbpdint or clamp for'operating it.

I, one of the lugs formed on socket of hammer.

The nature of my invention consists in providingl the ordinarynail-hammer, A B, with a4 chamber, C, to receive the head-end ofthe nailD, and a clamp, E, operatori by the thumb-point`H, and which clamp issecured by a spring, G, for retainingthe nail in said chamber untilentered into the place intended to be driven into. This entering, aslight tap accomplishes, and when thus stuck, the adhesion overcomesthe-force of the spring, and enables the hammer to vbe disengaged fromthe nail by lifting it. Then the ordinary face of the hammer is u sedfor driving the nail home. l

The lugs, one of which, I, only, shows in the drawings, is formed on thesocket of the hammer, and forms a slot for the reception of the tongueof the clamp. The tongue has a hole corresponding with the lugs, and thescrew F secures the clamp between the lugs. The spring-G passes betweenthe lugs I, and is riveted at its long end in the chamber'C. The-shortend presses on the -sole of the clamp, as shown on the drawings, the

whole being very simple and eleative.

lVhat I-claim as my invention, and desire to secure by Letters Patent,is

The application, to. nail-hammexsol-a nail-clamp attachment, using.fortl1at purpose the chamber C, the clamp E, the spring G, the lugs I, andscrew F, constructed to`operate`substantially as herein described.
